A considerable computation time is required to produce a wind resource map since numerical analyses ofcomputational fluid dynamics on a number of wind directional sectors are needed to be performed. Inconventional numerical analysis, a wind speed profile of the atmospheric boundary layer introduced from thefar upstream is assumed as an initial condition. In the present study, a reconfiguration method of initialconditions was applied by mirroring the converged solution with regards to 180-degree opposite wind direction,taking the symmetry of wind flow field and topography into consideration. The present study performed a windresource mapping case study for an island area considering 12 wind directional sectors using WindSim softwarewith 3 million grid cells and verified a reduction of computation time by approximately 50% after applying thereconfigured initial conditions. If the proposed method was extensively applied to all wind directional sectors,a total computation time was reduced by approximately 25% when applying existing methods to six winddirectional sectors and the reconfiguration method to the other six wind directional sectors. Thus, the proposedmethod is expected to contribute to the reduction time of project schedule when wind resource assessment isperformed in the future.
